First, pressurize. Exert certain pressure on muscles to adjust the balance of exercise strength. Strengthen muscle strength and reduce swelling to some extent. During exercise, muscles are stimulated, metabolism is accelerated, and water in muscle cells is increased, resulting in the feeling of cell swelling. Proper pressure helps to make exercise easier and more powerful.

Second, support. Hard waist protection can provide some support during exercise, hold the excessively bent waist, relieve muscle strain and protect the waist from sprain or pain. Some functional waist protectors with metal sheets attached to the back can effectively provide greater support and avoid accidental injuries. This kind of waist protector usually has a higher back.

Third, keep warm. Double-layer or multi-layer materials have stronger heat insulation function than soft and comfortable waist protection. Athletes often wear less clothes in sports, but the waist radiates more heat, which is easy to catch cold, causing backache, cramps or stomach discomfort. Waist protection with thermal insulation can effectively maintain waist temperature, accelerate blood circulation, and prevent colds and some stomach discomfort.

Fourth, shaping. Strengthening cell metabolism, burning fat, adjusting tightness and applying appropriate pressure are helpful to lose weight and shape. In the sports related to the waist, the waist protector with pressure, heat preservation and sweat absorption can accelerate the decomposition of fat, which is an essential protective device for waist contraction and fitness.
